The bottom of the drum 200 is provided with particles such as cat litter so that the excrements discharged by the pet can fall on the cat litter to avoid contaminating the drum 200. After the pet excrement is completely climbed out of the drum 200, the drum 200 rotates to move the first gateway 210 upward. At this moment, cat litter and excrement in the cylinder 200 can roll in the cylinder 200 under the effect of self gravity, can make the cat litter evenly wrap up and cover on the surface of excrement, makes the excrement form great cubic. As the drum 200 rotates, the first screen 221 rotates to a lower position. At this time, the cat litter on the litter surface that is not wrapped can enter the fourth space 240 through the first mesh 221 under the effect of its own gravity, and the massive litter wrapped with the cat litter cannot pass through the first mesh 221 because the shape is large, and thus can be left in the third space 230. The drum 200 continues to rotate, and the separation plate 220 gradually forms a state in which the first mesh 221 is higher than other portions of the separation plate 220. At this time, the excrements slide down to the lower position of the third space 230 by the gravity thereof, and the cat litter is stored in the fourth space 240 because the lower portion of the separating plate 220 does not have the first mesh 221 structure. When the first inlet/outlet 210 is abutted to the feces collection port 112, the sealing plate 121 slides to open the feces collection port 112, the first space 110 communicates with the second space 120, and the feces fall into the feces storage 300 in the second space 120 through the first inlet/outlet 210 and the feces collection port 112 under the action of self gravity. Finally, the sealing plate 121 slides to close the excrement collecting port 112, the drum 200 is turned upside down, the cat litter returns to the third space 230 through the first screen 221 under the action of self gravity, and the first inlet and outlet 210 is in butt joint with the second inlet and outlet 111, so that the separation and collection of the excrement are completed. As shown in fig. 4, when the drum 200 rotates to separate and collect the stool, the first gateway 210 and the second gateway 111 are staggered, so that the second gateway 111 can be closed, and the odor emitted from the stool cannot be emitted from the casing 100, thereby playing a role of isolating the odor of the stool.
